These are solid microfiber cloths. I'm not sure why someone would need 100 of these as they are washable and reusable, but nonetheless, they are good quality and clean well and hold up well with regular use.

These microfiber towels are great. They have a variety of colors for your cleaning tasks. These microphone towels are long lasting and are machine washable. I would definitely recommend these for all your cleaning tasks.

I’ve used a lot of microfiber, and these stand out because of the extra-large size. They have a good "bite" for picking up dust but are soft enough that I’m not worried about scratching my car’s clear coat or my stainless steel appliances. They wash well without shrinking, though I’d recommend washing them separately to keep them from picking up lint from other fabrics.

The towels are great. My son helps detail our cars and used these to finish drying the cars and they were left spotless. No fibers came off of the towels, and the cars were left shiny and clean. Perfect for cleaning purposes!!!
